Objective To evaluate the effectiveness of enucleation for the treatment of huge hemangiomas. Methods From 1979 to 1998, enucleation was used for the treatment of hepatic cavernous hemangiomas in 126 patients, among them 18 with multiple tumors and 6 with centrally located lesions. For the tumors larger than 10 cm in diametre or located in theⅠ or Ⅷ segment of the liver, enucleation combined with intermittent inflow vascular occlusion was adopted. Results All cavernous hemangiomas in this group were enucleated successfully, there was no mortality. The median intraoperative blood loss was 1015?577*!ml(200*!ml~4*!500*!ml). Postoperative complications developed in 15 patients including pleural effusion in 10 and wound infection in 5. 54 patients were lost from follow up. None of the remaining 72 patients had recurrence at the follow up ranging from 6 months to 18 years and 4 months. Conclusion Enucleation of cavernous hemangioma of the liver is a safe and effective alternative to hepatectomy.

Objective To compare the diagnostic value of 3.0T and 1.5T magnetic resonance diffusion weighted imaging (DWI) in lymph node metastasis of gastric cancer. Methods Preoperative magnetic resonance examination was performed on 50 patients with gastric cancer by using Siemens 1.5T and 3.0T superconducting magnetic resonance imaging system, and the outcomes were compared with postoperative pathological results. The sensitivity, specificity and accuracy of the diagnosis in lymph node metastasis of gastric cancer were analyzed statistically. The apparent diffusion coefficient (ADC) values of lymph nodes were also evaluated for 1.5T and 3.0T magnetic resonance DWI. Results The sensitivity, specificity and accuracy of the diagnosis on lymph node metastasis of gastric cancer by 1.5T magnetic resonance DWI were 79.4 %, 81.4%and 80.0%, respectively, and the corresponding percentages of 3.0T magnetic resonance DWI were 84.6%, 79.7%and 83.1%. The accuracy rate of 3.0T magnetic resonance DWI was slightly higher than that of 1.5T in the diagnosis of lymph node metastasis of gastric cancer (χ2=5.451, P=0.020), but there were no significant differences in the sensitivity and specificity between the two groups (both P> 0.05). The accuracy rate of 1.5T magnetic resonance DWI in the diagnosis of lymph node metastasis of gastric cancer was less effective than that of the pathological diagnosis (χ2=7.410, P=0.007), but there was no significant difference between 3.0T magnetic resonance DWI and pathological diagnosis (χ2=2.450, P=0.120). The mean ADC values of metastatic and non-metastatic lymph nodes detected by 1.5T magnetic resonance DWI were (1.036 ±0.203) × 10-3 mm2/s and (1.476 ± 0.215) × 10-3 mm2/s (t= 6.813, P< 0.001), meanwhile, the corresponding values detected by 3.0T magnetic resonance DWI were (1.154 ± 0.183) × 10-3 mm2/s and (1.502 ± 0.264) × 10-3 mm2/s (t= 5.991, P< 0.001). The coincidence of the two methods for ADC value was favorable. Conclusions The diagnostic effect of 3.0T magnetic resonance DWI on lymph node metastasis of gastric cancer is better than that of 1.5T. ADC value provides a reliable imaging quantitative indicator for the determination of metastatic lymph nodes in gastric cancer, which plays a significant role in the clinical treatment options and prognosis of patients.

OBJECTIVE: To study the effects of Fuzheng Yiliu Granule (FZYLG)-medicated serum on apoptosis of liver cancer cells H22 from mice and its mechanism. METHODS: Liver cancer cells H22 from mice were incubated in culture media containing sera from rabbits medicated with different doses of FZYLG. Flow cytometry was used to examine the cell cycle and analyze the apoptotic rate of the H22 cells. The morphological changes of the H22 cells were observed by transmission electron microscope and the apoptosis related proteins Bcl-2 and Bax were examined by streptavidin-biotin peroxidase complex (SABC) method. RESULTS: FZYLG-medicated serum could influence the cell cycle and stop the proliferation of H22 cells at the G(1)/G(0) phase with apoptotic peak being detected. In culture media with FZYLG-medicated sera, the expression of Bcl-2 decreased while that of Bax increased as compared with that in culture medium with non-medicated serum (P<0.05). CONCLUSION: FZYLG-medicated serum can induce apoptosis of the liver cancer cells H22 by influencing the cell cycle, down-regulating the expression of Bcl-2 and up-regulating the expression of Bax.

Objective To explore the features of autonomic nerve function in reflux esophagitis (RE) patients, and the role of abnormal function in the pathogenesis of RE. Methods Twenty RE patients (RE group) and 18 healthy controls (HS group) all underwent heart rate variability (HRV) with meal stimulation to test the function of autonomic nerve. At same time, the endoscopic Los Angeles (LA) Classification, RE symptom score, Gastroesophageal reflux disease-health related quality of life (GERD-HRQL), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were evaluated in the RE patients. Of those, 12 RE patients were re-examined the function of autonomic never after 2 to 4 months [mean (3.7±0.8) months] of proton pump inhibitors (PPI) treatment. Results In fasting state, the sympathetic activity was higher in RE group than in HS group, while the parasympathetic activity was lower in HS group (P=0.022 and 0.034). Postprandial, the trend of autonomic functional change was the same in RE group and HS group. Postprandial, the sympathetic activity was negatively correlated with symptom score in RE patients; however, the parasympathetic activity was positively correlated with RE symptom score. The influence of meal on the balance of sympathetic and parasympathetic was negatively correlated with RE symptom score (r=-0.48, P=0.022). The influence of meal on the parasympathetic nerve was positively correlated with RE symptom score and GERD-HRQL score. After PPI treatments, RE symptom score, GERD-HRQL score, SAS score and SDS score were all significantly decreased in RE patients. There was no significant difference in autonomic nerve function before and after PPI treatment. Conclusions There is abnormal autonomic nerve function in RE patients, characterized by higher sympathetic activity and lower parasympathetic activity in fasting state. The autonomic nerve function is correlated with RE symptom score. The abnormal autonomic nerve function may be one of the causes of RE.

The perioperative indexes and postoperative abdominal infection were compared between the two groups.Results:In intracorporeal anastamosis group, the intraoperative bleeding was (45.2±4.2) mL, the operative time was (161.3±22.4) min, the number of lymph node dissection was (30.8±9.6), the postoperative exhaust time was (3.3±1.2) d, and the postoperative hospital stay was (7.6±0.5) d. In extracorporeal anastamosis group was (42.1±5.0) mL, (167.3±26.7) min, (32.9±8.6), (3.4±1.0) d and (7.5±0.6) d, respectively, there were no significant difference between the two groups (t value were 0.417, 0.207, 0.829, 0.338 and 0.293, respectively; P value were 0.699, 0.845, 0.231, 0.734 and 0.802, respectively). In intracorporeal anastamosis group, the incidence of abdominal infection (with anastomotic fistula)was 13.9%(11/79), the incidence of abdominal infection (without anastomotic fistula)was 10.1%(8/79), and in extracorporeal anastamosis group was 1.5%(2/131)and 0.8%(1/131), the differences were statistically significant (χ 2=12.805, 10.238; P=0.003, 0.008). In intracorporeal anastamosis group, the incidence of respiratory system infection was 1.3%(1/79), the incidence of urinary system infection was 2.5%(2/79), the incidence of surgical incision infection was 1.3%(1/79). In extracorporeal anastamosis group was 3.1%(4/131), 0.8%(1/131) and 3.1%(4/131), respectively.There were no significant difference between the two groups (χ 2 value were 0.662, 0.420 and 0.662, respectively; P value were 0.364, 0.587 and 0.364, respectively). Conclusion:Laparoscopic right hemicolectomy with intracorporeal anastamosis and extracorporeal anastamosis have the same surgical effect, but intracorporeal anastamosis may increase the risk of postoperative abdominal infection.
